Good morning! Here's an update on what's coming up:
- This weekend, Chris will be traveling to the datacenter in Philly and installing six new solid state disks. The disks will increase the number of coins we can host, and will also permanently resolve the issue of the mining server hanging when Debian needs to access the network disk (and the subsequent problem of out of memory crashes due to the temporary ramdisk that took up some of the memory.) The mining server will be offline for 15 minutes and some coins will be offline for an hour at a time on Friday night. We will notify users when these disks are ready to be installed tomorrow evening.
- Some balance forfeitures occurred yesterday due to a bug that was discovered. While that sounds bad at first, all users who received "forfeitures" actually came out way ahead. More information is at viewtopic.php?f=4&t=2039.
- We had to disable a few coins because we discovered an issue that we had never considered before. While we limit the number of dynamic coin miners assigned to a coin, there is no limit to the number of static coin miners assigned to a coin. That means that the static miners can push the block times down very low, at the coin developers' and dynamic miners' expense. Next weekend, I'll implement a fix to prevent additional connections once there is too much hashrate on some easy coins.
- We determined that live total hashrates are being underreported. Before hashrate can be calculated, we use an average value, which we thought was 100 MH/s for scrypt but actually was 293 MH/s yesterday. The change will be applied on Friday when the mining server is restarted.
- Chris made some additional changes to our VPN setup in the hopes of resolving more of the "network errors" issues. Feel free to comment if you had some of these issues.
